Patent GB-872355-A (GB)
Title: Improvements in or relating to the production of a tetrabasic acid and esters thereof
Inventor: MAGGIOLO ALLISON
Filed: 1960-04-26
Abstract: 2.3.5-Tricarboxycyclopentaneacetic acid is produced by reacting one molar proportion of dicyclopentadiene with substantially two molar proportions of ozone in a medium comprising a carboxylic acid at a temperature of 10 DEG -45 DEG C. so as to obtain the diozonide and thereafter oxidising the resulting diozonide to 2.3.5-tricarboxycyclopentaneacetic acid, at least the final stage of the oxidation being effected with hydrogen peroxide in the presence of an acid having an ionization constant at least as great as that of formic acid.  Suitable carboxylic acids for use in the ozonization step are, for example, formic, acetic, propionic, butyric, valeric, caproic, heptanoic, caprylic, pelargonic or capric acid and mixtures thereof.  If desired additional inert liquids, e.g. esters, such as ethyl acetate, or water may be present.  Preferably formic acid is used in the ozonisation step and this is suitable to serve as the acid in the oxidation step without further addition of other acid. The oxidation is carried out preferably at 50 DEG -103 DEG C. and may be effected, for example, partly by treatment with oxygen alone, oxygen with traces of ozone, or by hydrogen peroxide in acetic acid. For at least the final stage of the process the oxidation is carried out by hydrogen peroxide in the presence of an acid at least as strong as formic acid i.e. having an ionization constant of at least 2.14x10-4 e.g., sulphuric, nitric, phosphoric, benzene sulphonic, trichloroacetic or trifluoroacetic acid, or formic acid itself.  The acid may be converted into esters by methods known per se and examples are given of the preparation of the tetramethyl and tetrabutyl esters.  Examples are given of the preparation of the acid using hydrogen peroxide in the presence of sulphuric acid, formic acid, and trifluoroacetic acid as oxidising agents.  When sulphate ions are present in the product they may be removed by ion exchange treatment.

Title: Process for performing endothermic reactions in blast apparatus
IPC: G01L3/08
Filed: 1931-05-19
Abstract: Relates to processes for the performance of endothermic reactions in blast-roasting apparatus, e.g. of the Dwight-Lloyd type, and consists in lowering the proportion in the charge of substances which absorb heat during decomposition, but which do not react with the fuel of the charge, by the addition of inert substances, such as sinter returns, to such a degree that the endothermic reaction, and, if desired, complete sintering can be carried to completion by a given fuel content in the charge.  The process is applicable for cement making, the burning of limestone, dolomite, magnesite, gypsum, &c., for the decomposition of chlorides and sulphates, e.g. ferric sulphate, zinc sulphate, lead sulphate, for reduction purposes &c. An example of a charge for Portland cement comprises 25 kg. of clay, 75 kg. of calcium carbonate, 100-120 kg. of sinter returns and sufficient coke breeze or like fuel to give 60-70 thousand calories.

Title: Fire ranging method for launchers of self-propelled missiles
IPC: F41G3/00
Filed: 1973-03-28
Abstract: 1380531 A fire ranging method CONSTRUCTIONS NAVALES ET INDUSTRIELLES DE LA MEDITERRANEE 28 March 1973 [19 April 1972] 14994/73 Heading F3C In a fire-ranging method for launchers of selfpropelled missiles the angular deviation between the theoretical trajectory of the missile and the point where combustion of the acceleration propulsive charge ceases is measured, and the launcher is subjected to angular movement in the opposite direction and with an amplitude proportional to that of the measured deviation, the proportion factor being constant for the type of missle in question and determined experimentally. The angular deviation is measured by logging on a grid the position of the missile at the end of the combustion phase or by following the missile with a reticle. A television camera and receiver assembly may serve as a sight. In a trajectory deviation of a self propelled missile as shown in Fig. 1, the straight line AX represents the trajectory without wind effect and the curve AY represents the trajectory when the missile is subjected to a side wind V. The speed of the missile at A is very low and deviation caused by the wind is at a maximum. The deviation then decreases to maintain a stable value from the instant at which the combustion of the propulsive acceleration charge is completed. The trajectory of the missile is now purely ballistic. An angle c to obtain the desired correction of the trajectory is acquired from the formula c=a/k where a is the angle defined by the straight lines AB and AX and K is the proportion factor.

Title: Improvements in or relating to telephone systems
IPC: H04Q3/00
Filed: 1939-05-22
Abstract: 529,644. Automatic exchange systems. MERCER, R. (Associated Telephone & Telegraph Co.). May 22, 1939, No. 15248. [Class 40 (iv)] In a system in which a permanent loop or ground condition causes a calling line to be locked out of service by the locking up to the line of the cut-off relay or by some other electrical connection to the line at the exchange, a test operator is enabled by a manual operation to exercise control over the test switch train to remove the connection to enable the line to be tested. The line circuit, Fig. 1, is such that a permanent loop condition due to a fault or standstill condition with the receiver off the hook or ground on the negative wire causes the cut-off relay K to be held over the loop, the line relay L being released. A test operator plugs testing equipment into jack J<SP>1</SP>, Fig. 2, and dials the number, the impulses being repeated by A to vertical and rotary magnets V, R of the test distributer, Fig. 5, in known manner, relay EA being held after the second digit. If the test final selector, Fig. 6, is busy battery over the release magnet ZM thereof operates G, Fig. 5, which returns busy tone and reverses the feed over leads M1, M2 to give a flashing signal. If the test final is idle, H operates and the third and fourth digits are repeated to the vertical and rotary magnets VM, RM of the test final. Relay EA is released on the third digit but pulls up again during the fourth. If the line is idle, RC operates in series with the line and cut-off relays and puts the test distributer into condition for repeating single impulses to the test final for stepping it further around the level, if desired. If the line is busy, RC does not operate but G pulls up during the slow release of E whereupon the flash signal is given but not the tone since FS is now operated. If the line is locked out due to a fault &c., RC is shunted sufficiently for it to remain inert and the operator who receives the busy signal may challenge the line to ascertain that it is not being used for conversation. To initiate a test, the operator throws key KT to operate TT which connects the test leads ST1, ST2 to the jack in place of the setting leads Ml, M2. If the line is faulty he also throws key KPG to operate FL over lead ST1, relays G and H being already operated. Relay FL short-circuits a winding to make itself slow and energizes FLA which initiates the release of FL. Relay FL opens the short-circuit on the secondary of transformer TF and in conjunction with FLA sends a pulse of high voltage over the third wire to operate the line relay L which disconnects the cut-off relay K from the loop but both relays remain held in series with RC, Fig. 5, which releases G so that the test connection over wipers W1, W2 is now clear of extraneous connections.
